IMO, the intuitive thing to happen there is for the various hits (if
any) to be removed from the beat subdivision and placed in the
clipboard. Are you thinking of an alternate behavior in which Cutting
takes the beat subdivision out of the bar (i.e. the bar loses a beat,
going from 8 to 7)? That doesn't make sense to me. If I select a
character in my word processor and Cut it, the page size doesn't change.
I can see that someone might want to shorten a bar, but that kind of
operation doesn't seem like the way of going about it.
Maybe it's more like dealing with tables in a word processor or layout
program. Cutting and pasting cells (or rows and columns) works a little
differently than cutting and pasting characters within them. In
Framemaker, for example, you are usually offered the option when Cutting
either to take the contents of the cells but leave the cells themselves,
or to take both the cell contents and cells. Pasting is similar, where
you are given the option to replace existing cells or to insert.

Being given the option to replace or insert would take take care of that
quandry. Though that said, if I was pasting into selected beat
subdivisions, I would expect my selection to be replaced by the
clipboard material. If I was pasting from a blinking cursor, I woulld
expect an insert.

If I had to go with one option, this seems the most intuitive.

I think modelling the behavior on the kind of behavior already found in
word-processor/layout table editing would come pretty close to a
reasonably flexible solution. I'm not sure how far that analogy can be
taken in practice, but it's the first thing that comes to mind! I think
the idea of a choice between copying/cutting/pasting either a container
(beats) or a container and its contents (beats + plus drum hits) would
not necessarily be that confusing.
